CVE-2025-40149

CVE-2025-40149 affects the Linux kernel TLS path: get_netdev_for_sock() could trigger a use-after-free if sk_dst_get(sk)->dev is used during setsockopt(). The fix replaces sk_dst_get() with __sk_dst_get() and dst_dev_rcu() in get_netdev_for_sock(), and notes that the only user of ->ndo_sk_g...

kernel: Linux kernel: Denial of Service in xsk_diag due to use-after-free during socket cleanup

A flaw was found in the Linux kernel's xskdiag interface. This vulnerability, a use-after-free error, occurs when the xskdiag interface is used after a socket has been unbound from its device, such as during socket closure or device removal. A local attacker could exploit this flaw to cause a...

kernel: smc: Fix use-after-free in tcp_write_timer_handler()

In the Linux kernel, the following vulnerability has been resolved: smc: Fix use-after-free in tcpwritetimerhandler. With Eric's ref tracker, syzbot finally found a repro for use-after-free in tcpwritetimerhandler by kernel TCP sockets. 0 If SMC creates a kernel socket in smccreate, the kernel...

kernel: rxrpc: Fix a race between socket set up and I/O thread creation

A flaw was found in the Linux kernel's rxrpc module. A race condition exists during the setup of a socket and its associated I/O thread. A remote attacker could send a specially crafted User Datagram Protocol UDP packet, which might be processed by rxrpcencaprcv before the I/O thread is fully...

kernel: net: af_can: do not leave a dangling sk pointer in can_create()

In the Linux kernel, the following vulnerability has been resolved: net: afcan: do not leave a dangling sk pointer in cancreate On error cancreate frees the allocated sk object, but sockinitdata has already attached it to the provided sock object. This will leave a dangling sk pointer in the sock...

kernel: virtio/vsock: Fix accept_queue memory leak

A flaw was found in the Linux kernel's virtio/vsock subsystem. Due to a race condition during socket destruction, incoming connection requests can be added to the queue after it has already been cleared, leaving unreleased sockets in memory. A local attacker could exploit this timing issue to cau...
